Sure there is. Have a look at the emerge man page, there 's lots uf useful 
information. portage also has a nice man page.

emerge --resume --skipfirst
This resumes the last emerge, skipping the first package. Leave 
the --skipfirst to try again. I like to use "FEATURES=keepwork 
emerge --resume" to resume an interrupted emerge without restarting from 
scratch, but this feature seems to be broken at the moment.

Maybe, but on the other hand it's a little bash one-liner.

This will emerge world and continue after every error, skipping that 
package:
emerge world -u || while ! emerge --resume --skipfirst; do :; done
